I'm still very interested in the kit. I'm very happy to see some detailed photos.
I'm building a 2.3L stroker with a ported & polished head. The BR440 I've got now might end up running out of it's efficiency range on this new motor. I don't really know yet since I don't have a compressor map for it. I'm looking at either a GT30R or a GT35R if the BR440 blows too hot. I'm still trying to figure out the most accurate way to calculate corrected air flow to plot it out on the maps to see which compressor is the best fit. Estimating VE has me stumped.
This is a daily driven street car first and a road race car second, I can't really tolerate any slower spool or increased lag than what I've got with the BR440.
How much extra is it to have the dump tube routed back into the downpipe?

No major updates yet. The car is on the road and running great, but at lowered boost and power levels for now. We actually have to finish other work
We're hoping to have the car back on Saturday for more testing... although the owner doesn't seem to be complaining to much.
I'll post more updates as soon as they are available.
negativeB: Give me a call if you have any questions.

Hey guy's I was looking at the picture's on page 1, post # 5, the last one with the turbo, manifold connected to downpipe & wastegate.
I noticed the downpipe has a dent in it...why is this? Was it done to tighten the bolts for d/pipe flange to turbo??? Is this a problem with the kits?
But other than that...this kit looks GREAT.
Respec.

You should get a bit more hp by dumping the wastegate tube vs. routing it back into the downpipe because it creates less turbulence inside the downpipe. Plus you should hold boost better with the dump.
